Connection to the external telephone network is typically through one or more ISDN PRI
trunks.
Each PRI port can be configured to support up to 23 simultaneous calls.
• Connect each PRI port to an ISDN PRI trunk, using standard Ethernet cables.
Note – Some installations may require a PRI swap cable or swap adapter to reverse the
transmit and receive pairs.
